A hybrid external cavity laser and a method for configuring the laser having a stabilized wavelength is disclosed. The plug-in power supply comprises a housing having arranged therein a voltage transformer module for converting a mains voltage into the required low voltage, and an exchangeable mains plug unit with at least two mains plug pins. The filter connected downstream separates high-frequency signal components from the output signal of the temporal median filter and suppresses high-frequency signal components with a high amplitude. The septum is formed of a resilient material and is connected to the base member by the stake, with a first portion of the septum contiguous with the stake fixed in position with respect to the base member and a second portion of the septum engaging the valve seat and covering and sealing the at least one inlet port. There are a variety of techniques by which this may be performed, one of which is by using dynamic programming alignment to compute alignments between articles. In one embodiment, a laser light source, a collimator lens, and a cylindrical lens are on the reverse surface of a chassis with reference to mounting references prepared on the reverse surface, while a reflective return mirror, a polygonal mirror, and f lenses are mounted on the front surface with reference to mounting references prepared on the front surface.
